Answer:
2g + 69
Step-by-step explanation:
Since 3g and g has the same variable: g, you can directly evaluate their co-efficients: 3 and 1.
3g - g = (3-1)g
= 2g
2g+69
The answer is just 3g being subtracted by g, or 1g, which will give you 2g. Then, you can't do anything with the + 69 because there is no other numbers to go with it to change, so it stays the same.
Hope it helps!
